5 Programming Languages a Professional Programmer Should Learn

Software Development is one of the most dynamic fields, constituting of various programming languages. Out of these hundreds of programming languages, choosing the best to learn is quite complicated. However, in this age, learning only one programming language isn’t enough. Gaining fluency in multiple programming languages will help you become more and more experienced and at the end of the day, that’s what all employers are looking for.

Companies will always prefer multilingual programmers who can write complex programs and scripts easily. Learning more than one language such as C++ and Java is considered mandatory for senior developers. Here we have created a list of the top 5 programming languages every techie should learn. We have chosen them based on their range of use, model and popularity among coders.

Top 5 Programming Languages Every Techie Should Learn

1: Java

Java is ranked as one of the most popular programming languages in use over the last two decades. It is used in application development in Android, mobile games, and web development. According to Oracle around 3 billion mobile phones and 89% desktop computers use Java.

Learning Java will help you to build strong, accessible server-side applications. Java can help you create complex projects easily using its variety of tools and tech. Udemy has a nice course “The Complete Java Master Class” which can help you learn Java and its important concepts. Here is also a list of Free Java Courses if you are interested.

The average salary for a Java developer is $85,000. This language isn’t confined to Java developers and Java engineers; it is also a requirement for any software engineer or developer.

2: Python

Python is a high-level programming language which emphasizes code readability. It is one of the easier programming languages to learn with the use of common words and expressions, more white spaces and fewer curly brackets. Python is also one of the most taught programming languages in schools and colleges and is even replacing Java as a starter language in courses.

Python can be used for scripting and as a language for larger projects. It is used by NASA and Reddit, and its web framework Django powers Instagram and Pinterest apps. It now has machine learning libraries such as TensorFlow, Scikit-Learn, and others. Its scope is mostly based on newer generation tech such as AI, data sciences and machine learning etc. Many companies are looking for Python/Django developers.

If you are a beginner interested in learning Python then you should join The Complete Python BootCamp. Also, take a look at this list of free Python courses for beginners.

JavaScript has dominated the whole world in the last five years. It is essentially a scripting language but is used for user interface development using a framework and libraries such as Node JS, Angular, and React.

It is mainly a scripting language used for making web pages more interactive. It is mostly text-based, written in HTML and then used through web browsers. According to Coding Dojo, it is used by over 80% developers and nearly 95% of websites use JavaScript for dynamic logics on their sites.

One of the reasons for JavaScript’s huge success is jQuery which helps the use of JavaScript on the client side. It helps to decide which feature is to be implemented server-side and client-side etc. Udemy offers an online in-depth Complete JavaScript course on JavaScript for beginners. You can also take a look at this list of free JavaScript courses for beginners.

4: C Programming

Some people believe that you cannot be a true programmer unless you know C or C++. It is a very integral language that a programmer must know and one of the oldest mainstream programming languages today. It is a general programming language that can be used to create small or large applications. It is used for system and application software, game development, client-server applications etc.

The language itself is more complex to learn and many prefer Python and JavaScript over it but it is still more preferred for system programming. You can learn many key programming concepts through C Programming such as structure, array, pointers, memory management etc. Also, all major Adobe applications are developed using C++ (which is quite similar to C).

If you are a beginner you can learn C through the C Programming for Beginners online. Also, check out this list of FREE C++ Coursesfor beginners.

5: Scala

Scala is a functional programming language based on the practices of the last 20 years. There are many functional programming languages to choose from but Scala is far easier than the others for e.g. Haskell. Scala is also more preferred to some because of its relevance to Java developers. However, C++ programmers may prefer Haskell.

In the end, you should decide which functional programming language you wish to learn by its demand in the market. You should learn the kind of programming language you will invest in your career. If you are a beginner then Beginning Scala Programming is a nice course, to begin with.

Learning programming languages isn’t enough; you must also learn the coding and design principles to become a pro in this field. As a programmer, you should have one language which is close to systems such as C or C++, one object-oriented language such as Java and Python and one functional language such as Scala or Haskell, one scripting language such as JavaScript.
